an ".isomem" extension is recognized
to cause a non-contiguous ISO
to be copied to RAM first.
It will try to write the sdx4 phantom partition
but perhaps it would boot anyway.
Yes!
The new version does work on a read only media!
It does not fail if it can not write the dbx4 partition!

I have only used the Easy2boot once or twice
and did not understand it and ended up with
non contigious error too often due to me on fat 32

So I went over to your isobooter instead that always
create a new contigious fat32 and is even more easy to use.
At least for me.

Thanks my questions was not clear enough.
I never heard of the technical term isomem
so I asked more about how does it come up at all
and what cause it and how to avoid it and so on.
Is it GParted that created it or is it the Iso Devs
that chose to include it or is it a kind of error warning or what?_________________I use Google Search on Puppy Forum
not an ideal solution though

Isomem is a good idea (Steve website for tech detail), but (in my opinion) bad result at the end.
Some you may to know:
How big/fast is your physical ram/computer?
How big is your iso file to be copied to ram memory?
How long is the copy process?
How long is the iso booting until you get your desktop?
You will find out some of copied iso will not boot at all.
You can not run isomem from ntfs.

Direct iso booting is better to go and/or anyway frugal booting is the most reliable.

Tried this using isobooter but failed two times in a row.
Started anew each time. The error it gives are that it fail to find
the mbr signature file? so most likely it is Suse that has set up
something unique for them when one boot this iso

So the Suse software expect that everybody provide such file
but would they not include some exception in the boot up script
that realize on boot on old hardware with not UEFI active?

You know these things way above my grasp so I can only share
my surprise that the Devs of Suse would send out an ISO
that fail to boot on old gear? No big deal. Fedora booted
but them had no Adobe Flash so no use for me.
Crunchbang, Linux Mint LXDE, Solyd Linux, Solus Linux and Zorin linux
all of them have Adobe Flash so I have enough rescue usb now that boots

Thanks indeed for your isobooter. So much easier to boot other linuxes this way. Fast set up and boot and works almost like Puppy no need for to be Sudo or root at all. one can do almost anything and it ask nothing or complain_________________I use Google Search on Puppy Forum

-h, --help print this message and exit
-v, --version print the version information and exit
--root-directory=DIR install GRUB images under the directory DIR
instead of the root directory
--grub-shell=FILE use FILE as the grub shell
--no-floppy do not probe any floppy drive
--force-lba force GRUB to use LBA mode even for a buggy
BIOS
--recheck probe a device map even if it already exists

INSTALL_DEVICE can be a GRUB device name or a system device filename.

grub-install copies GRUB images into the DIR/boot directory specfied by
--root-directory, and uses the grub shell to install grub into the boot
sector.

I want to tell to you about my experiments. By unetbootin I created a usb stick persistent of lubuntu 13.04. Unetbootin uses a file as casper-rw. I found that my install was too slow running from usb stick so I wanted to transfer the install to hd using grub2 to boot the iso. I had not success to make recognized the casper-rw file of the usb-stick copied to hd. If someone has success in this I beg him to tell to me how. But I achieved another result. I copied by pudd the original casper-rw file to a usb-stick partition. Then labeled the usb stick partition as casper-rw. Now booting the lubuntu's iso by grub2 from hd it recognize the original persistent install casper-rw in the usb-stick. Now my lubuntu is fast enough.
